Yes, in the end this is what I ended up doing. For the archives, I
calculated the magnifcation which would be required to rotate a page
and fit it into 4.25x5.5. Turns out that its between \magstep2 and
\magstep3, so I'm using:
\magnification=\magstep3
And then using psnup to rotate the pages and fit two onto one 8.5x11
page. The text is then about the right size.
Thanks for confirming my course of action on this.
